Hm, it's going to be alot more unfun if you do keep going, it'll caues you alot more problems then just being unfun!
I use to drink like a fish because i to found it made me more of a fun person to hang around everyone loved me when i was drunk. When i was sober i was boring as no one cared to talk to me much. But then i realised "i'd rather be hated for who i am then loved for who i'm not!" (however that quote goes. so true).
I can't give you much advice, as i just woke up oneday and my body couldn't handle anymore booze i'd feel sick 24/7 it made my anxiety worse (gosh the hangovers from when i did drink my my anxiety worse), so yeah i just stopped..
but if you think your developing a problem, i mean try to stop.. but if you can't do get help! it's so much easier to kick the habit now then it will be in months or years to come..
and there most definately will be people in the world who find you fun just being you! and for the people who don't.. who cares they arn't worth knowing...
